In a lake a remote controlled submarine moved norweast at a constant velocity . It moved 935 centimeters in 10.0 seconds. What was its velocity

93.5 m/s

Explanation:

Velocity is the rate of change of displacement per unit time. It is measured in metres per second.

i.e velocity = Displacement / Time taken

In this case,

Displacement = 935 centimeters north west

(Convert centimeters to metres)

Recall that 100cm = 1m

935 cm = 935/100 = 9.35m

Time taken = 10.0 seconds.

So, velocity = Displacement / Time taken

Velocity = 9.35 metres x 10.0 seconds

Velocity = 93.5 m/s

Thus, the velocity of the submarine moving north west is 93.5 m/s

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
